title: Sigmoid colon fistula complicating ovarian cystadenocarcinoma: a rare finding.
abstract: A case of sigmoid colon fistula complicating ovarian cystadenocarcinoma is reported. The entity demonstrated a large air-filled, thin-walled cystic lesion during barium enema examination. The differential diagnosis of distended air-filled cystic lesions is discussed and expanded to include colonic fistula complicating ovarian neoplasms.
